这里简要记录 Python核心编程 读书笔记 整段代码 可以直接运行

CODE-主线程

# -*- coding:gb18030 -*-
# 主线程
from time import sleep, ctime
def loop0():
    print 'start loop 0 at: ', ctime()
    sleep(4)
    print 'stop loop 0 at: ', ctime()
def loop1():
    print 'start loop 1 at: ', ctime()
    sleep(2)
    print 'stop loop 1 at: ', ctime()
def main():
    print 'Starting at: ', ctime()
    loop0()
    loop1()
    print 'Stop at: ', ctime()
if __name__ == '__main__':
    main()

RESULT-主线程

Starting at:  Wed Aug 09 18:35:47 2017
start loop 0 at:  Wed Aug 09 18:35:47 2017
stop loop 0 at:  Wed Aug 09 18:35:51 2017
start loop 1 at:  Wed Aug 09 18:35:51 2017
stop loop 1 at:  Wed Aug 09 18:35:53 2017
Stop at:  Wed Aug 09 18:35:53 2017
Process finished with exit code 0

CODE-多线程

# -*- coding:gb18030 -*-
import thread
from time import sleep, ctime
def loop0():
    print 'Starting loop 0 at: ', ctime()
    sleep(4)
    print 'Stop loop 0 at: ', ctime()
def loop1():
    print 'Starting loop 1 at: ', ctime()
    sleep(2)
    print 'Stop loop 1 at: ', ctime()
def main():
    print 'Starting at: ', ctime()
    thread.start_new_thread(loop0, ())
    thread.start_new_thread(loop1, ())
    sleep(6)
    print 'Stop at: ', ctime()
if __name__ == '__main__':
    main()

RESULT-多线程
